Subject: crypto/zuc: remove check for SSE4
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=541ce1c7074c1c0cec531c5e9d4081908f1680e5;hp=cfcb2003c00f900a00d62c7b4518f3d935751b06;p=dpdk.git

crypto/zuc: remove check for SSE4

Since SSE4 is now part of the minimum requirements for DPDK, we don't need
to check for its presence any more.
